Add NOT NULL checking of pg_stat_statements_reset() in tests

This is preliminary patch.  It adds NOT NULL checking for the result of
pg_stat_statements_reset() function. It is needed for upcoming patch
"Track statement entry timestamp" that will change the result type of
this function to the timestamp of a reset performed.

Expand regression tests of pg_stat_statements for utility queries

This commit adds more coverage for utility statements so as it is
possible to track down all the effects of query normalization done for
all the queries that use either Const or A_Const nodes, which are the
nodes where normalization makes the most sense as they apply to
constants (well, most of the time, really).

This set of queries is extracted from an analysis done while looking at
full dumps of the regression database when applying different levels of
normalization to either Const or A_Const nodes for utilities, as of a
minimal set of these, for:
- All relkinds (CREATE, ALTER, DROP)
- Policies
- Cursors
- Triggers
- Types
- Rules
- Statistics
- CALL
- Transaction statements (isolation level, options)
- EXPLAIN
- COPY

Note that pg_stat_statements is not switched yet to show any
normalization for utilities, still it improves the default coverage of
the query jumbling code (not by as much as enabling query jumbling on
the main regression test suite, though):
- queryjumblefuncs.funcs.c: 36.8% => 48.5%
- queryjumblefuncs.switch.c: 33.2% => 43.1%
